Building a tool from scratch that may exist already... am I reinventing the wheel? Does this already exist?

Hey everyone, happy Sunday!

So I have been working on a personal project over the past few years off and on that essentially does the following:

- Manages and scales a set of Docker instances hosting a web API
- Manages incoming requests to the api. These requests are then routed to the Docker instance that my tool deems fit, and then the Docker instance "owns" it
- Maintains state for all of the Docker instances, which requests they are hosting, and their metrics.

But long story short, I'm beginning to worry that this could be done with modern tools that already exist, in a better fashion. For example: Use some sort of reverse proxy like apigee to handle the incoming api requests, and then use something else to manage the state and load of what these instances are hosting. Then use traditional k8/docker swarm to use these metrics to tell when to scale the solution out.

Does this all sound like something that exists currently, and when is it a good idea to maintain an internal tool with a high LOE for changes over a set of existing platforms in combination?

Know of any good sample resources for automated testing?

I'm setting up some training material for Web UI automated testing as well as API Web service automated testing.

Do you know of any good sample web applications and sample web services that I can pull down from GitHub (or wherever) and deploy to write these 2 types of automation against?

Ideally a sample e-commerce site and a REST web service with a few endpoints to cover the basic GET, POST DELETE would suffice.

The idea is to focus less on the deployment and setting up of the website & web service and more on making a good test suite for whichever someone may encounter. It doesn't matter to me which language these are and I can deploy to either Linux or Windows--no preference there either.

Thanks for your help!

Lost my job because of the virus. Anyone else in the same boat?

I've been a remote DevOps worker for the last two years. Our industry is in event hosting, naturally with all the closures work came to a halt as profit was down to zero.


I'm just a contractor without a contingency plan. I thought I would be safe because my work was remote, but I was on the first chopping block. Now I have no idea where to start looking for something else.

Is there a good self-serve tool for infrastructure deployments?

The company I am in has been growing beyond the scale of our DevOps team and I was wondering if there is a tool that allows for sane self-serve deployments of cloud resources like Kubernetes clusters, network policies, etc...

My main requirements are:
- IAC (Can be rebuilt from scratch with code)
- Simple setup
- Low maintenance
- Preferably open source

Things I looked at:

- Rundeck(Not IAC)
- Ansible Tower (unreliable)
- Writing my own( don’t wanna reinvent the wheel if there is one)

Thanks

Your own Kubernetes controller - Laying out the work

It’s hard nowadays to ignore Kubernetes. It has become the ubiquitous platform of choice to deploy containerized applications.

>Kubernetes is an open-source system for automating deployment, scaling, and management of containerized applications.

In a few years, Kubernetes has entrenched itself deeply in the DevOps landscape under the tutelage of the Cloud Native Computing Foundation. One could speculate about the reasons. IMHO, one very compelling argument is that it allows users to be independent of the API of a single cloud provider. If you’ve been living under the monopoly of Microsoft on the desktop in the 2000’s, you probably know what I mean.

Another reason for Kubernetes to be so widespread is that it’s relatively easy to extend it. In fact, it’s so easy a lot of software providers who offer a Docker image also provide one more operators.

In this 3-parts post, I’ll describe how to start implementing your own controller in a language other than Go, assuming zero knowledge of the subject but Kubernetes itself.

What is your preferred cloud service to manage a postres db?

I'm most experienced with mongo and atlas, but right now I'm working on a side project and for sure want to go with postgres, but there are a lot of cloud service options for that and I'm kind of overwhelmed by them and in rush. So what's your favorite? Preferably it'd be low cost.

This project has 35 million+ users and that's going up fast so it'll be useful to have a redis cache as well to reduce db calls.

While the number of reads will be really high, the number of total documents and writes will be relatively small to begin with.

Tomorrow I will be telling story tales for engineers

Hello everyone.

I am convinced that if you explaining something to a group of people who are engineers like you, you do not need to go deep into details, because I assume that tech people can understand the idea even without knowing to many details. But tomorrow I am going to explain what is devops to such group of engineers. Suddenly I come up with idea not to used tech language but try to make up imaginary situation or even story which have to draw the picture in their minds. Short story long. What do think? Is it good story to tell?

Imagine you are pirates. Our company is a ship, dev teams are ship crew. The ship crushed and when storm died down we found out that most of us are on island, somewhere in the ocean. Our main goal is to survive because nobody knows when we will be rescued. After stand-up meeting we decided to start building house and make the island our temporary home. We have to act quickly. The thing need to be done first, is to gather remainings of the ship, and everything that could help us survive. When we were done. It turned out that one group of people collected all the tools an instruments, another group, all the food we had on the ship. Of course there were people who collected nothing but they had experience which is nevertheless very helpful in such situation. Every time when group of people have something valuable they will convince the others that something they have is the most important thing and everybody should obey them. No doubts without tools we can not build houses and we can not get by without food. What if group of people which owns tools starts limiting the access to these tools? What if the group of people which owns food starts using food for manipulating the others? Probably we end up in fighting and arguing. Instead of finish building in 7 days we will have finished in 20 days if we will be lucky. As you probably have understood, group of people is the team, things they possess, is silos, house is the application. In order to finish building house on time we have to work together as one team. Our responsibility is not to keep safe the stuff we own, instead we are responsible for final result, for building house, for building application.

Intern with a lot of struggles with Consul Connect

Hi

For my BA I'm doing in an internship with another student, where we have to research Service Mesh in Kubernetes. But we're having a big struggle with consul connect.

We wanted to setup circuit breaking (a envoy proxy feature) while using bookinfo (the sample application from the Istio guys). Do you guys have any tips how to configure the envoy proxies?

Installing consul was easy but configuring the proxies are giving us a hard time because it's the first time for us. Or do you guys have some easy examples?

Hope you guys can help :)

Cheers!

What is the cheapest way to run my program on AWS?

I have a small python bot to handle all my PR on instagram and facebook for my small business. What is the cheapest way to run my program once a day for its duration and shut down.

Ive looked into Lambda a little bit and think it might be what i'm looking for. I was also looking at the aws boto library for writing a script that would launch and instance and shutdown when complete.

Any insight would be very helpful=)

Which APM are you using to monitor your .NET core and JAVA services?

Hi all

Currently we are checking the solutions to monitor our services on high load

Our existing monitoring:
- AppDynamics: in some cases it can add 20% of overhead. Performance issues if you are using the latest technologies and libraries
- NewRelic: Cost is unbelievable

There are some solutions which we want to check - Atatus and Dynatrace but I want to know your feedback and recommendations

Can you please share what are you using?

Really appreciate your suggestions

Good ways to “fail over” to new DNS target (in event of downtime)

Currently using a fairly popular DNS provider to point our domain name to our app(s).

In the event that any target servers go down for an extended period of time, what are some quick and effective ways to transfer to a static page to control the messaging?

What are some best practices around this sort of thing?
